Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific examples.
Referring to fig. 1 to 3, fig. 1 is a flowchart illustrating a method for preventing cracking of a splicing seam of an assembled wall panel according to an embodiment of the present invention; FIG. 2 is a schematic view of the splice joint perpendicular to the front view of the exterior wall surface; FIG. 3 is a cross-sectional view of the splice seam.
The embodiment of the invention discloses an anti-cracking method for splicing seams of an assembled wallboard, which comprises the following steps:
the first step is as follows: performing seam filling and jointing treatment on the splicing seam 2 by using a jointing material, and cutting a stress release groove along the jointing position;
because the width of the splicing seam 2 between the wallboard and the structural beam plate and between two adjacent wallboards is generally influenced by factors such as the specification and installation error of the wallboard, the width of the splicing seam 2 is inconsistent, and accordingly, the preset width is changed within a certain range. In this embodiment, the preset width is preferably 5mm, which can be adjusted according to the implementation. Of course, the splice seam 2 may also be a crack in the wall due to stress.
The caulking material can be cement mortar, structural adhesive, tile adhesive, waterproof mortar or special cement, and the like, and can also be other building caulking materials.
The stress relief groove 1 is cut along the center of the pointing by a cutting machine, so that stress concentration caused by the tendency bending of the stress relief groove 1 is prevented. The depth range of the cut stress relief groove 1 is 0.5-50 mm, and the preferred depth range is 5-10 mm.
The second step is that: filling the cementation sealing layer 3 into the stress relief groove 1 until the cementation sealing layer 3 extends out to the groove edge of the stress relief groove 1 until the cementation sealing layer extends to the surface of the outer wall;
when the cementation sealing layer 3 is filled in the stress relief groove 1, the stress relief groove 1 and the groove edge thereof need to be cleaned in advance, so that the cementation sealing layer 3 can play a good sealing role.
The cementation sealing layer 3 is a flexible building sealing material, and can be building caulking paste, building sealant or elastic putty. The building caulking paste can adopt a nano caulking paste, and the nano caulking paste is prepared from the following raw materials in parts by weight: 60-80% of acrylic emulsion, 0.5-2% of fumed nano-silica, 0-10% of titanium dioxide, 0-10% of hollow ceramic particles, 1-25% of mica powder, 1-15% of talcum powder and 0.5-5% of auxiliary agent. The building sealant can adopt polyurethane, modified silane, polysulfide, silicone and other materials which meet the relevant standard building sealant.
Considering that the preset width is 5mm, the outward-spreading width of the cementation sealing layer 3 from the groove edge of the stress relief groove 1 is more than or equal to 5mm, and the sealing effect is further improved.
The third step: before the cementation sealing layer 3 is not set, a T-shaped crack repairing strip 3 or a matrix material is pasted on the cementation sealing layer 3 filled in the stress relief groove 1;
after the T-shaped joint strip 3 is installed and flattened, the T-shaped joint strip 3 can be coated and covered by the cementing sealing layer 3 again.
The key point is that the central symmetry plane of the T-shaped joint strip 3 is superposed with the central symmetry plane of the stress release groove 1, namely the T-shaped joint strip 3 is arranged at the center of the stress release groove 1, so that the T-shaped joint strip 3 is prevented from being insufficiently sealed. The T-shaped seam filling strip 3 can be made of PVC materials or metal materials, the thickness range of the T-shaped seam filling strip is 0.1-2 mm, and the thickness range is preferably 0.5-1 mm; the width range is 4-50 mm, and the preferred width range is 10-20 mm. The specific size of the T-shaped patch strip 3 may be set according to practical circumstances, and is not particularly limited herein. The carcass material can be specifically glass fiber mesh cloth.
The fourth step: and (3) coating a cementing and sealing layer on the surface of the T-shaped joint strip 3 or the carcass material, so that the cementing and sealing layer completely covers the T-shaped joint strip or the carcass material.
The fifth step: the outer wall decorative surface layer is arranged on the periphery of the T-shaped seam repairing strip or the matrix material to be consistent with the surface of the outer wall, so that the attractiveness of the building is improved, and the service life of the building is prolonged. Of course, an outer wall waterproof layer and a putty layer can be arranged on the T-shaped seam repairing strip or the carcass material, and the painting sequence of the outer wall waterproof layer, the putty layer and the outer wall decorative surface layer 4 can refer to the prior art, and is not described in detail herein.
The method for preventing the assembled wallboard splicing seam from cracking provided by the invention is described in detail, a specific example is applied in the method for explaining the principle and the implementation mode of the invention, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
